LS3 pump on an LS1?
What all do I need to install an LS3 pump on my 99 LS1? Mine went and I hear this is a nice upgrade. Also where do I purchase the pump. None of the parts stores in my area could get them.
Summit has them but they are bucu bucks cause they only sell the replacement from GM.
Thanks!

Also do you know if the LS3 pump is a direct bolt on for the LS1 or does it require some tweaking to fit? Somebody told me they thought the pulley may be positioned slightly differently.
Thanks!

Where did you get the LS3 pump from? And what type of tstat does it take? Just a regular SBC tstat? I need a 160 degree as my car has been reporgrammed.
